application filed infer 7, 1924. Serial no. 1097,4524.

To all whom it may concern.

Be it known that we, LEONARD H. BROWN,

a citizen of the United States, and a resident of North Palo Alto, in the'county of Sap an Mateo and State of California,

RUDOLPH MALMGREN, a citizen of. the United States, and resident of Mayfield, in the county of 'Santa Clara and State of California, have invented certain new and useful-Improvements in Paintbrush Protectors, of which the following'is a specification.

After a brush has once been used in paint, especially the heavier brushes such as used, in house, painting, it must be thoroughly cleaned or some means provided to prevent access of-air thereto, otherwise the oxidation of the exposed paint soon forms a hard coating on the body portion of the brush and particularly upon the brush proper at the base of the bristles. Furthermore, even when cleaned the used brush rapidly loses its pliancy and shape even when immersed in: a protecting liquid.

It is one object of our invention to provide a device so formed and constructed as' to be readily closed over the bristles and fitting snugly against the brush body whereby to'eflectively seal the same off from the air when not in use. Q It is aiiother object of our invention to provide a device of the character indicated that is so formed as to maintain the bristles in their, proper compact normal wedgeshaped condition when not in use.

Furthermore, it is an object of .our invention to provide .a device of the character indicated provided with means for seeuringit firmly-in a closed position on a brush.

Finally, it is an object of our invention to provide a device of the'character indicated that will be economical to manufacture, easily made in various sizes to accommodate various sizes of brushes, offew arts, simple in construction, and highly e cient in its practical application. I

In the drawing:' r

Figure 1 is a frontelevation'of the device in position on a brush.

Figure 2 is a side elevation of the samef Figure 3. is a section on line 3-3 of Fi re 1. I

' igure 4 is a sectional view through another embodiment of ,our invention.

Referring more particularly to'the draw-1 themselves to form receive the edges 9f thereby forming the under surface of body" ing an outwardly extending tion t e ing, 1 and 2 indicate the two side portions 66' hin ed together, at 3 and, provided with we ge shaped end portions 4. The edges-pf the end portions g ofpart l'are folded u on grooves 5 adapted to portions 4. of part 2," a tig t joint when the two parts are folde together on a brush.

In its practical application, several sizes of these devices are made to conform. to the several standard sizes of brushes, the combined upper edges of parts 1 and 2 being so formed and proportioned as to fit snugly around the brush and butting up against portion 6,. the y latter carrying-a handle 7.

The interlocking side edges, hinged bottom edges and snugly fitting top edges ef} fectually seals the bristle portionof the brush oif from contact with theair and consequently preserves the brush in a soft and flexible condition. Furthermore, since the shape of the device conformscloselyto the, shape of the brush, it causes the brush to retain its normal shape when not in use.

The combined features of preventing the drying of the paint on the brush and maintaining it in. a normal shape greatly increases the. effective life of the brush and obviates the necessity of spending consider; I able time in cleaning the brush-every time itis laid aside for a little while. In order to positively secure the two parts 1 and'2' ina closed position on abrush in close contact with the body ortion 6 thereof, any suitable clamp may e used such as spring elements 8 hingedly mounted as at 9 on one element as 1 and capable ,of being swung into the positions clearly shown in Figure 3 to gras the element 2. v

If it is desire to secure the device to the brush a suitable fastener may be used. In the present case we show a member 10 mounted on the deviceas'shown and carrylip 11 provided with an eye 12. On mem er 10 and adjacent to eye 12 is formed a button or boss 13. At 14 we show a resilient strip provided with a hooked end 15 adapted to en age the upper surface'ofbod'y portion '6, the other end being provided with orificeslti adapted to engageboss 13, the said strip passing throu h e e 12. By means of this construcd evice may beheldfirmlyin posi-' the preferred embodiments of our invention, changes in form, construction and method of operation may be" made within the scope of the appendedclaims.

We claim 1. A paint brush protector comprising a pair of-jaws hinged together at one end and having triangular shaped interlocking sides, and an element mounted thereon and extending beyond one end thereof and adapted to engage the body portion of a brush placed therein.

2. A paint brush protector comprising a pair of jaws hinged together at one end and having triangular shaped interlocking sides, and a longitudinally adjustable'spring element mounted thereon and adapted to engage the body portion of a brush placed therein.

gagement with the other of said jaws Whereby to hold said jaws in closed relation to each other.

4. A paint brushprotector comprising a pair of jaws hinged together at one end and having triangular shaped interlocking sides, a. longitudinally adjustable spring element mounted thereon and adapted to engage the body portion of a brush placed therein, and spring elements mounted upon one of said jaws and adapted to be swung into engagement with the other jaw whereby to hold said jaws in closed relation to each other.
